* tty: replace ->proc_fops with ->proc_showChristoph Hellwig2018-05-1614-172/+16

* ide: remove ide_driver_proc_writeChristoph Hellwig2018-05-161-46/+0
| | | | | | | | The driver proc file hasn't been writeable for a long time, so this is just dead code. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: "Eric W. Biederman" <ebiederm@xmission.com>
* isdn: replace ->proc_fops with ->proc_showChristoph Hellwig2018-05-1615-110/+20

* atm: simplify procfs codeChristoph Hellwig2018-05-161-58/+7
| | | | | | | | | | | | Use remove_proc_subtree to remove the whole subtree on cleanup, and unwind the registration loop into individual calls. Switch to use proc_create_seq where applicable. Also don't bother handling proc_create* failures - the driver works perfectly fine without the proc files, and the cleanup will handle missing files gracefully.
